First of all: I know that I can manually create a bunch of config files with corresponding patterns for every locale; actually I try to find a workaround with using only IntlDateFormatter.
我会尝试用例子来解释。
<?php
$tz = new DateTimeZone('Europe/Moscow');
$now = time();
foreach (['en_US', 'ja_JA', 'ru_RU'] as $locale) {
printf("%s:\n", $locale);
foreach ([IntlDateFormatter::MEDIUM, IntlDateFormatter::LONG] as $datetype) {
$formatter = new IntlDateFormatter($locale, $datetype, IntlDateFormatter::NONE);
printf("- %s\n", $formatter->format($now));
}
}
这产生
en_US:
- Feb 1, 2016
- February 1, 2016
ja_JA:
- 2016/02/01
- 2016年2月1日
ru_RU:
- 1 февр. 2016 г.
- 1 февраля 2016 г.
我需要
en_US:
- Feb 1
- February 1
ja_JA:
- 02/01
- 2月1日
ru_RU:
- 1 февр.
- 1 февраля
第一个想法是为给定的语言环境提取模式并删除任何“y”和“Y”字母。但正如您所见,年份不仅仅是 4 位数:所有逗号、斜杠、标签(如“г.”和“年”)。
附言:
实际上,我想要的理想 IntlDateFormatter
实现是一种智能模式,其中所有组件都各就各位,但我可以配置每个组件要使用的模式。比如:'d MMMM y г.'
模式不是 ru_RU
格式化程序有一个 'dmy'
模式,而对于 d
组件它有 d
模式,m
- MMMM
和 y
- y г.
。所以我可以说 y
组件是一个 ''(空字符串),瞧。
此外,如果您知道任何图书馆已经这样做了——请告诉我。

所以,目前这是不可能的。我发现 intl
PHP 扩展缺少 DateTimePatternGenerator
( http://userguide.icu-project.org/formatparse/datetime ),这正是我所需要的。
The DateTimePatternGenerator class provides a way to map a request for a set of date/time fields, along with their width, to a locale-appropriate format pattern. The request is in the form of a “skeleton” which just contains pattern letters for the desired fields using the representation for the desired width. In a skeleton, anything other than a pattern letter is ignored, field order is insignificant, and there are two special additional pattern letters that may be used: 'j' requests the preferred hour-cycle type for the locale (it gets mapped to one of 'H', 'h', 'k', or 'K'); 'J' is similar but requests no AM/PM marker even if the locale’s preferred hour-cycle type is 'h' or 'K'.
For example, a skeleton of “MMMMdjmm” might result in the following format patterns for different locales:
locale | format pattern for skeleton “MMMMdjmm” | example ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ en_US "MMMM d 'at' h:mm a" April 2 at 5:00 PM es_ES "d 'de' MMMM, H:mm" 2 de abril, 17:00 ja_JP "M月d日 H:mm" 4月2日 17:00
另外,我发现 HHVM 已经实现了它 — https://github.com/facebook/hhvm/commit/bc84daf7816e4cd268da59d535dcadfc6cf01085 .我希望有一天这会被移植到 PHP。
